Transseptal BATMAN for High-Risk Valve-in-Ring Procedures: A Case Series

Valve-in-ring procedures represent a feasible solution for high-risk patients with surgical repair failure. The risk of left ventricular outflow tract obstruction increases the challenge, and transcatheter approaches to prevent it are technically demanding and often do not resolve it. We demonstrate the feasibility and safety of a transseptal balloon-assisted translocation of the anterior mitral leaflet for valve-in-ring implantation.
